This system provides an effective mechanism for generating and delivering a computer-controlled personal reminder regardless of what application program is executing. The system is based on an independent time-keeping process. On the IBM PC, under PC-DOS, this process can be a device driver as described below. Under other operating systems on the IBM System/370, the process can be performed by a separate virtual machine or a task running without an attached terminal. The independent time-keeping process (REMINDER DEVICE DRIVER) is used to control the storing and delivery of reminders. The device driver is a piece of virtual hardware that acts like an input/output device. An application program, such as a calendar, can write reminders to the REMINDER DEVICE DRIVER which then acts as a storage device and clock watcher.
